You may need to flash a different kernel or you may need to flash a bootloader and baseband that is compatible with the installed ROM.

How about you use kies and flash the stock rom?

Can you please elaborate, i'm not sure what kies does or how to use it,
I have tried flashing couple stock roms and all had the same problem.
Install Samsung kies(jellybean) or kies 3(for kitkat). Then click on tool tab and click on firmware upgrade and initialisation. Enter the phone model and S/No as shown on the back of your phone. and it will download your stock rom which might help you restore your imei.
Also you can try this post. http://forum.xda-developers.com/showthread.php?t=1857054
